1.	Hirudin isA. a protein produced by Hordeum vulgare, which is rich in lysineB. a toxic molecule isolated from Gossypium hirsutum, which reduces humn fertilityC. a protein produced from transgenic Brassica napus which prevents blood clottingD. an antibiotic produced by a genetically engineered bacterium Escherichia coli
Answer» Correct Answer - C Hirudin is a protein that stops blood clotting. The gene encoding hirudin was chemically synthesised. This gene was then transsferred into Brassica napus, where hirudin accumulates in seeds. The hirudin is purified and used as medicine.
